The Effect of Aerobic Training on Tumor Necrosis Factor alpha, Hypoxia-Inducible Factor-1 alpha & Vascular Endothelial Growth Factor Gene Expression in Cardiac Tissue of Diabetic Rats
Objective: The goal of this research was to determine the influence of 4 weeks aerobic training on gene expression of tumor necrosis factor alpha (TNF-α), hypoxia-inducible factor-1 alpha (HIF-1α) and vascular endothelial growth factor (VEGF) in the cardiac tissue of diabetic rats. Materials and Methods: In an experimental study, 30 male wistar rats were partitioned into three groups (n=10), d...
متن کاملgene expression profiling for cancer targeted therapy
background : lung cancer is still the leading cause of cancer- related deaths and most of themâ are normally diagnosed in late stages, so there is an urgent need to establish reliable tools for the identification at early stages of the disease. in this study, we use an eleven gene signature test to examine lung biopsy specimens for diagnostic, prognostic & therapeutic purposes. methods : bronc...
متن کاملTargeted Replacement of Hypoxia-Inducible Factor-1A by a Hypoxia- Inducible Factor-2A Knock-in Allele Promotes Tumor Growth
Hypoxia-inducible factors (HIF) are essential transcriptional regulators that mediate adaptation to hypoxic stress in rapidly growing tissues such as tumors. HIF activity is regulated by hypoxic stabilization of the related HIF-1A and HIF-2A subunits, which are frequently overexpressed in cancer cells. To assess the relative tumor-promoting functions of HIF-1A and HIF-2A directly, we replaced H...
متن کاملHypoxia-inducible expression of tumor-associated carbonic anhydrases.
The transcriptional complex hypoxia-inducible factor-1 (HIF-1) has emerged as an important mediator of gene expression patterns in tumors, although the range of responding genes is still incompletely defined. Here we show that the tumor-associated carbonic anhydrases (CAs) are tightly regulated by this system. Both CA9 and CA12 were strongly induced by hypoxia in a range of tumor cell lines. In...
متن کاملHypoxia-inducible mir-210 regulates normoxic gene expression involved in tumor initiation.
Previous studies have suggested that the HIF transcription factors can both activate and inhibit gene expression. Here we show that HIF1 regulates the expression of mir-210 in a variety of tumor types through a hypoxia-responsive element. Expression analysis in primary head and neck tumor samples indicates that mir-210 may serve as an in vivo marker for tumor hypoxia. By Argonaute protein immun...
